If I’ve got the point properly, you want to download your item which is soft-rejected. It’s not working because a soft rejected item should be improve by the author then author will be able to re-submit it. In this case you have the item on your own system and you don’t need to download it from MarketPlace.

By the way, if you’ve lost the item on your own system, you may open a ticket and ask support to send you the file if it’s available somewhere…

because this is not done here … they just consider that this is not uploaded and approved and thus should not be stored in the site , which make sense … but sorry to ask, why do u need to do this? u don’t have it on your computer any more? if so, that’s a mistake as not only u should keep until this is approved, but, in addition, u should have a backup somewhere to make sure that u do not lose your work

You actually CAN download soft-rejected items. If there isn’t a button, it doesn’t mean you can’t download them. Go to the URL of the soft-rejected item, take the ID from the URL(the last number in the URL) and open this URL manually http://themeforest.net/user/YOUR USERNAME/download_own_source_files/YOUR ID
